Green Lake Falls

Green Lake Falls is the largest waterfall in the Bacon Creek basin and one of the largest waterfalls in the state of Washington. The falls occur as Green Lake’s outlet stream rolls over the side of the glacially carved upper valley of Bacon Creek and veils, cascades and plunges around 980 feet. The drop begins with a broad, steep sliding veil type horsetail fall where the creek runs across slightly channeled granite. A portion of the creek is diverted into a distinct channel which features a powerful roostertail at its immediate top, with the majority of the creek sliding down the main channel. This drop measures approximately 320 feet in height and about 120 feet wide. At the base of the veiling drop, the creek immediately reverts to a more gradual set of cascades without pause, accounting for another 200 or so feet in elevation, before spreading out across a broad shelf and dropping over the second substantial part of the falls, a roughly 460-foot tall sheer plunge-into-horsetail style drop, which consistently stretches 200-feet wide, and during high water periods can span as much as 360 feet in width due to multiple additional channels forming. The stream along which Green Lake Falls occurs is a significant but unnamed branch of Bacon Creek which heads in the Green Lake Glacier on Bacon Peak. The basin which the falls drain lies at elevations at or above 4200 feet above sea level and receives heavy snow fall during the winter months. Coupled with the substantial size of the glacier and Green Lake itself, the volume of water which can be present in the stream during the peak of melt season can be considerable, and this helps to solidify Green Lake Falls as one of the most significant waterfalls in the Pacific Northwest, if not the United States. Like most streams in the northwest, during the late summer months the volume of water in the falls will drop considerably from its peak spring and early summer flows, but the presence of the glacier and lakes ensure that the falls retain a consistently moderate to above moderate flow throughout the year. Due to the rugged terrain and fairly remote location Green Lake Falls is exceptionally difficult to access, let alone observe and this made it quite difficult for us to obtain much of the information needed to provide an accurate survey of the falls. Height figures and dimensional measurements presented in this survey report were obtained via both topographic map data and aerial images available on Google Earth and Bing Maps and should be considered approximate (though well within a reasonable representation of reality).
